  • Trace Analysis of PAHs using EPA methods 3541, 3545 and 8100

    The Extraction System B-811 and the Syncore Analyst parallel concentrator from Buchi as well as the Pressurized Solvent Extractor from Applied Separations were evaluated for the pretreatment of samples containing PAHs. Recoveries of extraction and subsequent concentration using acetone-n-hexane (1+1) were 70-95% for 2 ring and 90-100% for less volatile 3-5 ring PAHs. A good ...

  • Field Hydraulic Conductivity Tests for Compacted Soil Liners

    Field hydraulic conductivity tests are required to determine the in situ hydraulic conductivity of compacted clay soils used in the liners for hazardous waste management facilities. The test must be capable of measuring hydraulic conductivities of 1 × 10-9 m/s or less, and the values obtained must be representative of the overall soil liner. Few of the methods available are capable of both ...

  • Ammunition Manufacturing

    An ammunition manufacturing facility was having problems removing copper and zinc from their 900 gpm wastewater system. The process used lime to raise the pH from 1.5 to 10, sodium carbamate for a metal precipitant, and an anionic flocculant to increase the flock size and get the solids to settle in the clarifier. Current chemical costs are estimated at $225,000/year with a significant amount of ...

  • A comparison of microbial contact bioassay with conventional elutriate assays for evaluation of wastes hazard

    The aim of this investigation was to develop a battery of bioassays - contact and elutriate tests with Bacillus pumilus, elutriate tests with Daphnia magna and Paramecium caudatum, for the assessment of the wastes' toxicity. The contact test with B. pumilus was more sensitive than the elutriate test. The estimated LID10 were much higher for Daphnia and Bacillus tests than for Paramecium test. No ...
